Linear Technology’s Dust Networks product group premiered the SmartMesh LTC5800 (system-on-chip) and LTP5900 (module) families, said to be the industry’s lowest-power IEEE 802.15.4E compliant wireless sensor networking products.
SmartMesh ICs and modules enable tiny sensor ‘motes’ to be designed with a battery life of over 10 years, while companion network manager components enable the development of highly robust and secure wireless sensor networks (WSN).
SmartMesh networks use a triple-play of wireless mesh technologies – time diversity, frequency diversity and physical diversity – to assure reliability, resiliency, scalability, power source flexibility and ease of use.
At the core of this technology is an intelligent mesh network with advanced algorithms and power saving technologies that enable powerful features. These include deterministic power management and optimisation, auto-forming and self-healing mesh technology, zero collision low-power packet exchange and scalability to large, dense, deep networks.
Two communication standards are supported: the SmartMesh IP version is compliant with the 6LoWPAN standard, providing native IPv6 addressability to every node, while the new SmartMesh WirelessHART IEC62591-compliant products double the battery life over the prior release.
All SmartMesh networks are centrally managed, which provides comprehensive security and network management capabilities. The SmartMesh WirelessHART manager (LTP5903) can support up to 500 nodes per network, SmartMesh IP managers can support up to 100 nodes per network, and multiple instances of SmartMesh subnetworks can be deployed side-by-side to create very large networks.
